I purchased Pilot Neox High-Purity Graphite Pencil Lead - 0.5 mm - HB, Uni-ball
NanoDia Low-Wear Pencil Lead - 0.5 mm - HB, and Pentel Stein Enhanced Silica
Pencil Lead - 0.5 mm - HB in one order, after looking at reviews for all the
0.5mm lead available on JetPens, trying to find the one that erased the best and
was longest lasting. I compared all three in a Rotring 800, on Rhodia 80g
paper(A very smooth paper), without twisting the pencil(So they were all worn to
the same point when I wrote with them). This was my least favorite of the bunch,
being significantly harder to erase(Harder compared to the perfect Pilot and
near perfect Uni-ball. It still erases well!). It leaves a slightly lighter line
than the Pilot, on par with the Uni-ball. This was the longest lasting of the
bunch, with the Pilot lasting half as long, and the Uni-ball lasting about 3/4
as long. It's very hard to break, I was able to write easily with about 7mm
outside of the pencil at once(Uni-ball was about 7mm, Pilot got a full 10mm).
All in all, all three were good leads that I would recommend to anyone. If you
prefer long lasting, get this. If you prefer easy to erase, get the Pilot. If
you want the best of both worlds, get the Uni-ball.

This is the HB lead I've been looking for all my life. Smooth, very little smear
if any, and strong! I just ordered the HB Soft and B as well. I annotate in the
margins as I read, and prefer to use pencil on the books that have thin paper
(my scriptures). This lead is the best for that purpose that I have found.

I ordered this lead and Pentel Stein 2B lead. I'm used to writing with
Hi-Polymer HB lead and I think this lead scratches the paper slightly more than
the Hi-Polymer. I'd suggest ordering the HB soft or B (since this lead is
relatively strong) if you like Hi-Polymer HB.
